My aunt mailed me a USB stick of iPhone photos. On her Mac they looked fine. On my Windows PC every file was HEIC and Photos kept asking for a Store extension. She did not want to pay for desktop software for a one-time favor.
That is the use case for convert HEIC to JPG free online: no install, no account, done in ten minutes.
What “free online” should mean
A decent free converter:
- Runs in Chrome, Edge, Firefox, or Safari
- Lets you pick JPG (or PNG/WebP if you need them)
- Handles more than one file when you have a whole folder
- Does not make you email photos to a stranger’s server
“Free” is not the hard part. Privacy is. For family photos I only use tools that decode in the browser (WebAssembly on your machine). You select files, they convert locally, you download. If a site asks you to create an account before you see a preview, I close the tab.
Our converter works that way — same idea as the longer step-by-step guide, just fewer clicks if you already know what you are doing.
Quick workflow
- Copy HEIC/HEIF files from iPhone (cable, iCloud folder, or however you usually transfer).
- Open the converter, drag the folder or select files.
- Choose JPG, set quality around 80–85% for normal sharing.
- Convert, then download one-by-one or as a ZIP.
On a phone you can still do it; a laptop is easier for fifty files at once.
When free online beats desktop apps
| Situation | Why browser wins |
|---|---|
| Someone else’s PC | No install rights |
| One-off batch after a trip | Not worth learning new software |
| Remote help over video call | “Open this link” works |
| You are on a Mac but recipients use Windows | Convert once, send JPG |
When I have thousands of files and no internet, I switch to desktop tools — see online vs desktop comparison.
JPG vs PNG vs WebP (short version)
- JPG — Default. Email, chat, print shops, old apps.
- PNG — Bigger files, lossless; screenshots or heavy edits.
- WebP — Smaller on modern sites; not every old tool opens it.

Limits to expect
Even good free tools cap how much your RAM can chew at once. If the tab freezes, convert in chunks of ~100–150 files. That is a hardware limit, not a paywall trick.
Some cloud converters are “free” because you upload the image. Fine for a public stock photo. Not what I use for kids’ birthday pictures.
If conversion fails on one file
- Re-copy from the phone (USB interrupted copies happen).
- Confirm the extension is
.heicor.heif. - Try another browser tab (Chrome or Edge are the least fussy in my experience).
